Title: False stereo sound reproducing device
Inventor: ISHIGAKI YUKINOBU
IPC: H04S1/00
Filed: 1979-06-04
Abstract: PURPOSE:To reproduce selectively monaural sound or false stereo sound automatically according to contents of the source, by stopping the reproducing operation of false stereo sound when the nmonaural sound signal is a signal dependent upon human's voice. CONSTITUTION:The monaural sound signal output from source 8 is phase-shifted in phase shifter 12 by a phase shift quantity different dependently upon the input signal frequency. The output of phase shifter 12 and the signal which does not pass through phase shifter 12 are subjected to addition and subtraction by adder and subtractor 10 and 11 and are reproduced and output as false stereo sound. Meanwhile, the monaural sound signal is input to a frequency select circuit consisting of band-pass filter 13, band-stop filter 14 and so on to discriminate whether the monaural sound signal is a signal dependent upon human's voice or not. If it is discriminated that the monaural sound signal is a signal dependent upon human's voice, an external control signal is output to electronic attenuator 21 to cut off the output of phase shifter 12.

Title: Plasma source and ion beam source using the same
Inventor: NISHIO RYOJI
IPC: C23C14/48
Filed: 1991-04-02
Abstract: PURPOSE:To provide a relatively simple device capable of generating a homogeneous plasma at high density and taking out a homogeneous broad ion beam of large current from the plasma. CONSTITUTION:When a metal 21 in a crucible 22 is evaporated by electron beam irradiation 36, a plasma is generated by thermal ionization of the vapor and collisional ionization with the electron beam and its secondary electrons, and thermions are emitted from the evaporating surface. A positive potential is applied to a box discharge electrode 10 provided with a fin 13 enclosing the evaporating part. The electrons in the plasma are accelerated to the electrode 10 and collided with the vapor in the evaporating part having a high density to ionize the vapor. In accordance with the electron inflow to the electrode 10, the thermions are replenished into the plasma, this thermion is also similarly accelerated to collusively ionize the vapor. Thus, a high density plasma is formed in the box electrode. When a high frequency is superposed onto the positive potential of the electrode, the ionizing effect is more enhanced. The ion in the plasma efficiently flows out from the ion output port 11 of the electrode 10 as a homogeneous beam.

Title: Motor-driven tilt display
Inventor: NAKAJIMA SUKEYUKI
IPC: G09F9/00
Filed: 1989-03-22
Abstract: PURPOSE:To eliminate a sensor and to simplify the constitution by automatically stopping a motor when the load of the revolving motor exceeds the set value. CONSTITUTION:When the switch of the motor 3 is turned on and a display 2 is turned in both arrowed directions A, the display 2 is abutted on the armor of an electronic equipment main body 1 and stops when the display 2 is turned with a fixed angle or above. At this time, since the motor 3 is loaded and excess current flows in the motor, the display 2 detects the excess current, interrupts the current and stops the motor. Thus, the position of an object to be moved is detected without using the sensor.

Title: Camera torque detector
Inventor: ONDA KAZUHIKO
IPC: G03B17/00
Filed: 1988-03-24
Abstract: PURPOSE:To smoothly and surely switch a power transmission route from a film winding system to its rewinding system by establishing a releasable engaging relation between a lock-stopper and a switch lever since the lock-stopper, which is loaded in the direction of compression, restrains the switch lever from turning. CONSTITUTION:When a film is completely wound up with the planetary gear 22 of a change-over planetary clutch mechanism 20 meshing with a winding gear 24, a torque detecting lever 33 detects the specified torque to displace the lock-stopper 40 while resisting an energizing means. The lock-stopper 40 is subjected to the turning force of the stretch lever 26 in the direction of its compression: therefore, when the lock-stopper is displaced by any force other than the frictional force which acts on the surface where the stopper is engaged with the switch lever 26, does not restrain it from being displaced. When the lock-stopper 40 is displaced, its engagement with the stretch lever 26 is released, and consequently the stretch lever 26 is not restrained by any means; ultimately the switch lever 26 receives turning force for turning. Switching the power transmitting route from the film winding-up state to its rewinding state, can thereby be executed readily.

CONSTITUTION:When measured values at the same time are necessary in the devices to be monitored 36 to 3n, a measuring person outputs a measuring control signal 31 in which measuring items and the address of the device 36 to 3n are described through a circuit 2. In the device 36 to 3n, it is received by a receiving circuit 21 respectively and a required frame is transferred to an interruption measuring control circuit 23 as a measuring signal 32. The circuit 23 stops it by outputting a stop signal 33 to a cyclic scanning control circuit 24 by the input of the signal 32, connects the circuit 23 with a measuring circuit 25 through a switch 26, outputs a measurement scanning address signal 34 according to the measuring item indicated by the signal 32 to the circuit 25, selects a measuring object by the circuit 25 and measures it. A measured value 36 is transmitted to a monitoring device at the reception of a selective call control signal 38. Thus, the measured values at the same time in the required device to be monitored can be collected at the device 1 side.

Title: Prevention of breakage of concrete pile in inner drilling final striking work
Inventor: WATANABE OSAMU
IPC: E02D5/72
Filed: 1986-03-31
Abstract: PURPOSE:To prevent the breakage of a pile by preventing the intrusion of soil into the downside of the pile when striking the pile by a method in which a ground stabilizer is injected with stirring into the downside of the pile set by inner drilling to form a closed portion on the tip portion of the pile. CONSTITUTION:A concrete pile 1 having a friction cutter 1a on its lower end is set by inner drilling by means of a spiral auger 2. A ground powder stabilizer 3 is injected with stirring from the tip of the auger 2 into the excavated soil advanced into the downside of the pile, and the auger 2 is pulled up and the stabilizer is hardened to form a closed portion 5. Striking is applied to the top of the pile 1 to penetrate the top of the pile 1 into the bearing stratum. Since the tip of the pile 1 is closed, soil does not go into the downside of the pile 1 when striking the pile 1. The length of time and the number of times of striking can be lessened without causing the breakage of the pile 1 by the internal pressure.
